kernel

The following parameters are available in the kernel status dictionary.

Time and resolution resolution doubletype - The resolution of the simulation (in ms) time doubletype - The current simulation time to_do integertype - The number of steps yet to be simulated (read only) max_delay doubletype - The maximum delay in the network min_delay doubletype - The minimum delay in the network ms_per_tic doubletype - The number of milliseconds per tic tics_per_ms doubletype - The number of tics per millisecond tics_per_step integertype - The number of tics per simulation time step T_max doubletype - The largest representable time value (read only) T_min doubletype - The smallest representable time value (read only)

Parallel processing total_num_virtual_procs integertype - The total number of virtual processes local_num_threads integertype - The local number of threads num_processes integertype - The number of MPI processes (read only) off_grid_spiking booltype - Whether to transmit precise spike times in MPI communication (read only)

Connector configuration initial_connector_capacity integertype - When a connector is first created, it starts with this capacity (if >= connector_cutoff) large_connector_limit integertype - Capacity doubling is used up to this limit large_connector_growth_factor doubletype - Capacity growth factor to use beyond the limit

Random number generators grng_seed integertype - Seed for global random number generator used synchronously by all virtual processes to create, e.g., fixed fan-out connections (write only). rng_seeds arraytype - Seeds for the per-virtual-process random number generators used for most purposes. Array with one integer per virtual process, all must be unique and differ from grng_seed (write only).

Output data_path stringtype - A path, where all data is written to (default is the current directory) data_prefix stringtype - A common prefix for all data files overwrite_files booltype - Whether to overwrite existing data files print_time booltype - Whether to print progress information during the simulation

Network information network_size integertype - The number of nodes in the network (read only) num_connections integertype - The number of connections in the network (read only, local only)
